An optical energy and optical signal transceiving and processing system based on single optical fiber integrated optical cable

Abstract

The invention provides an optical energy and optical signal transceiver processing system based on a single optical fiber integrated optical cable. It is characterized in that it consists of a user terminal control system, an optocoupler, a multifunctional integrated optical cable, a wavelength division multiplexing module, a photoelectric conversion module, a sensor port, a signal transceiver duplex module, a voltage regulator circuit and a function module. The invention can simultaneously realize the transmission of electric power, communication and sensing signals in the form of optical signals in a single optical cable. The optical signals in the system are optical signals of different wavelengths, so that the mutual interference is extremely small. There is no need for high-voltage instruments at the control end and output end of the system to realize the output and transmission of power, which reduces the complexity of the system design and improves the portability of the overall system. The invention can simultaneously realize remote energy transmission, communication and sensing signal transmission and reception, and can be used for remote monitoring, exploration and completion of special tasks in complex environments such as seabed and underground.

Description

technical field [0001] The present invention relates to an optical energy and optical signal transceiving and processing system based on a single optical fiber integrated optical cable, which can realize remote energy transmission and signal transceiving at the same time, and can be used in complex environments such as seabed and underground remote monitoring, exploration and special tasks.

Problems solved by technology

However, it also has obvious defects, and its main limitations are as follows: 1. The same body manufacturing, when there is a problem with one line in the cable, it cannot be replaced independently, and it may cause a short circuit of the cable when it encounters external damage such as lightning strikes and corrosion. Generate a large current, damage the equipment and damage the cable; 2. The shielding between the cable core and the fiber core is complicated, and the signals are easy to interfere with each other, which affects the use of the cable; 3. Long-distance power transmission is for high voltage Or ultra-high voltage (36kV ~ 500kV) demand, so that the corresponding equipment is required to generate output power at the user control end (power output end), and at the same time, corresponding circuit modules suitable for high voltage are also required at the power receiving end to realize power output. The processing and use of the system increases the volume, weight and complexity of the system, which limits the portability of the system, especially the user control end; 4. Since the power supply cable needs to use metal cores, such as copper wires, this makes the overall photoelectric composite cable The weight of the photoelectric composite cable is relatively large (the weight of the existing photoelectric composite cable is generally greater than 100 kilograms per kilometer). Difficult to use for rapid temporary submarine local area network laying and power and signal exchange for portable rapid underwater mission execution systems
